Abstract

AN AIR CIRCUIT BREAKER COMPRISING: A CAM (22) CONNECTED TO A ROTATIONAL SHAFT (21) TO BE ROTATED; A DRIVING LEVER (23) CONNECTED TO THE CAM (22) TO BE ROTATED; A CLOSING SPRING (25) CONNECTED TO THE DRIVING LEVER TO BE COMPRESSED BY THE ROTATION OF THE DRIVING LEVER (23); AND A PLURALITY OF LINKS FOR TRANSFERRING A TENSILE FORCE GENERATED WHEN THE CLOSING SPRING (25) IS TENSIONED TO A SWITCHING SHAFT (3) CONNECTED TO A MOVABLE CONTACT (38), WHEREIN AT LEAST ONE OF THE PLURALITY OF LINKS HAS A STRUCTURE THAT A PLURALITY OF MEMBERS ARE COUPLED TO ONE ANOTHER, WHEREBY OPERATION RELIABILITY OF THE AIR CIRCUIT BREAKER CAN BE ENHANCED AND A LIFETIME THEREOF CAN BE ELONGATED BY PREVENTING ABRASION OR DAMAGE FROM BEING OCCURRED ON THE LINKS DURING THE OPERATION OF THE AIR CIRCUIT BREAKER.
